| Zusammenfassung: | An ultrasonic flow measuring method comprises steps of selecting a section area in a right angle to an ultrasonic transit trajectory line for measuring a flow velocity as a section area necessary for a flow measurement; and multiplying a flow velocity component of a direction corresponding to an ultrasonic transit trajectory, which is directly measured by an ultrasonic wave, by the section area thereby to compute a flow or flowrate, so that a flow measuring error and a measuring error of a section area can be significantly reduced, thereby enhancing the accuracy of the flow measurement. |
